This error message indicates quite clearly that memory is *not* your
problem with this program. 'SIGFPE' (which you should recognize, if
you have ever programmed on a Unix box for numerical applications)
means: 'SIGnal: Floating Point Exception', i.e.: you've done something
illegal with floating point numbers. You'll need to debug your program
to find the exact reason. If you're used to debugging under Unix,
you'll probably want to choose 'gdb' as your debugger.
